Another winterization question

Assuming it will never really be in below freezing except while driving with heat on.. then if left overnight for a day or 2 it would be plugged in with the heat on.. All other times in heated factory...


Can you just completely drain the system and tank, run 5-10 gallons of antifreeze through the system till it comes out of the faucet pink , making sure to run through hot water heater and be good.. Also making sure the grey and black tank have at least a few gallons of Anti and that you also have run it through the discharge and macerator till pink

thx

You really don't want the pink antifreeze in the water tank or water heater. It stays there a long time after it's been drained. I'm not familiar with Interstates. Can you just drain the water heater and put it into bypass? Do you have a way to connect to the water pump so you can pump from the antifreeze jug to the lines? Using an air compressor to blow out the lines would be the best thing.

Maybe an Interstate owner can give you a better answer.
